Constant speed mode
For processes with constant vacuum demand, it is recommended to leave the PLUS vacuum pump running at constant speed.Pressure control mode
For processes with changing vacuum demand over time, the pressure control mode is the ideal choice. In this case the PLUS vacuum pump adjusts the rotational speed according to the required vacuum level.Once this vacuum level has been achieved, the PLUS vacuum pump continues to run at minimum speed, enabling it to respond to a sudden need for increased vacuum demand and leading to further energy savings.
R5 rotary vane vacuum pumps
In a cylindrical housing, a rotor with several vanes is mounted eccentrically. Due to centrifugal force, these vanes slide out and form chambers between themselves and the housing. The pumped medium is trapped inside these chambers. During further rotation, their volume is constantly reduced. Thereby, the pumped medium is compressed and transported to the outlet.COBRA screw vacuum pumps
Inside dry screw vacuum pumps, two screw rotors rotate in opposite directions. The pumped medium is trapped between the cylinder and the screw chambers. There, it is compressed, and transported to the outlet.FAQ
R5 PLUS vacuum pumps operate according to the proven rotary vane principle and are oil-lubricated. COBRA PLUS vacuum pumps are based on screw vacuum technology which works completely dry.
The Modbus TCP/IP protocol allows integration into any standard process control system.
On the large high-definition color touch screen power consumption, oil temperature as well as inlet and outlet pressure curves can be displayed and therefore easily be supervised. In addition, oil level and motor frequency are always in view.
All relevant parameters can be adjusted and monitored allowing a perfect match to every process.
Different operating modes ensure that PLUS series vacuum pumps always run in optimum operating condition. In combination with the intelligent pressure control, ECO mode settings and the auto restart function further energy and cost savings are possible.
All relevant parameters can be adjusted and monitored allowing a perfect match to every process.
The condition of the components, the event history and the running hours are recorded permanently. The required maintenance interval can thus be adjusted and indicated accordingly. As a result, service intervals can be longer and service costs can be reduced.
Warnings and alarms can be programmed for example if the oil temperature exceeds a certain level.
